Say you have two groups, A and B, and you want to run a 2-sample t-test on them, with the alternative hypothesis being: Ha: µ.a ≠ µ.b. You will get some test statistic, call it t, and some p-value, call it p1. If you then run an ANOVA on these two groups, you will get an test statistic, f, and a p-value p2.
